The value of \(x\) that satisfies the equation \[ \sin^{-1}(x)=\cos^{-1}\!\left(\frac{3x}{4}\right) \] is:
The value of \(x\) that satisfies the equation \[ \sin^{-1}(x)=\cos^{-1}\!\left(\frac{3x}{4}\right) \] is:
Show Hint
Always convert all inverse trigonometric terms to the same type (all sin-inverse or all cos-inverse). This allows you to set the arguments equal to each other.
